Thanks! For the body I used 2:1 contrast medium and Akhelian Green as suggested by a fantastic painter on this board, and then highlighted and evened it out with Baharroth Blue. The scales on the back and thighs are Talassar Blue right over the green and dry brushed with Lothern Blue.
The knife and scepter are Warp Lightning, highlighted with Sybarite Green and Gauss Blaster Green.
The loincloth is Blood Angels red, layered with Evil Sunz Scarlet, and highlighted with Wild Rider Red.
The helm and toe claws are Zandri Dust, shaded with Seraphim Sepia, layered with Ushabti Bone, and highlighted with Screaming Skull.
I'm gonna shoot for making the stone look like a varnished desert sandstone, but we'll see how that goes.
